Chapter extraction / insertion tools

[Mirx]

Are there any tools out there that that make chapter alteration easy. I got 1 disc, which if I run it through dvdremake won't get the chapter timings correctly. They shift a fraction of a second per cell. I have no idea which tools I can use to correct this manually. Probably has something to do with the fact that the stuff I'm working on is already ripped / altered / remuxed. So I'm not labeling this as a DVDRemake bug, but any hints to which programs I can use to fix this manually would be appreciated.

you can use Ifoedit to manually correct the cell times if you want do you know how the timecode is worked out? as it's rather simple

No I don't. Only thing I can find is the VTS_C_ADT table, where you can alter the cell ID's and sectors, but I can't figure out how the reference this to the correct times. So a link to some info or something would be great. And in the VTS_TMAPTI the discontinuity entry's which I suspect are the chapter points.

this is part of my post copied from another thread and tells you how the timecode value is created to keep the original timecodes you can easily copy the original overall PGC timecode. You can also just edit one of the blanked cells to make up for the missing timecode. Just take the original time and the blanked time and work out what is missing just in case you don't know how to work out a timecode here is an example original is 02:45:24.20 /25fps (2hrs:45mins:24secs:20frames) blanked is 01:50:21.04 /25fps the difference is 00:55:03:16 so to work out the decimal value you would simply create the hex value first 55 03 16 which is 55 for the minutes, 03 for the seconds and 16 is the frames. The hex value should also include whether it's 25 or 30 fps. If it's 25 frames per second you add 40 to the hex value (55 03 56). If you want to have it in NTSC (30fps) you add C0 (55 03 D6). Its probably easier to convert the original hex timecode you want into decimal first and then just add 64 for PAL or 192 for NTSC as Ifoedit uses decimal anyway you could create an excel file where you enter the timecodes for each cell and it will tell you the total time to enter at the top also to save all the maths it all depends on how much it's changed as to what way you would do it. Hope you follow as it's a rather crude explanation in relation to this thread

So I understand you correctly, I don't need to worry about the cell entry points etc. I just have to change the times in the VTS_PGC_1. I'll give it a try tonight. Thanks

I think so, good luck and let me know how it goes
